This invention relates to clamps, and more particularly to a vise forefficiently holding a fish hook during the operation of tying a fiythereon. :One object of this invention is to provide a device. of theabove nature in which the vise jaws are actuated by an eccentric cammember at the -rear ends of the jaws, whereby they may be operatedrapidly and efficiently, and the fly-tying operation will not beobstructed.

Another object is to provide a device of the above nature in which, theeccentric cam member. operates against an adjustable abutment,

whereby the jaws may be easily adjusted te clamp L vise as it appearsduring use.

Fig. 2 is a plan view of the vise jaws, partly in section, showing theeccentric cam member in clamping position.

Fig. 3 is a front end view of the same, as seen from the upper left ofFig. 1.

Referring now to the drawings, in which like reference numerals denotecorresponding parts throughout the several views, the numeral II]indicates an angular upright rod which is supported by means of aholding device in the form of a C-clamp H which has a clamp screw l2adapted to hold the clamp upon the edge of a table, shelf or otherhorizontal member T. The C-clamp II is provided with a vertical bore l3within which the rod I is fitted, and has a set screw I4 which isadapted to adjustably hold the upright rod ill in its forward position.

The rod II) has an upper portion l5 which is rearwardly inclined and hasa reduced cylindrical extremity l6 which is locked in the apertured rearend of a stationary jaw I! by means of a key-pin l8.

It will be thus seen that the stationary jaw I! is carried in aninclined forwardly-extending position at right angles to the upperinclined portion l5 of the upright rod Ill.

The vise includes a short movable jaw [9 which is attached to a centralportion of the stationary jaw ll by a pivot means in the form of a pair1 Claim. (Cl. 81-25) of plates '20, 2| which carry a pivot pin 22 andare secured to the upper and lower faces, respectively, of the'jaw 11 bymeans of a pair of rivets 23 passing therethrough. The jaws ll, I3 areof any suitable material such as hard steel, and are preferably providedwith a dull finish, whereby annoying reflection of light willbe avoided.

The jaws l1, l9 have front end portions 24, 25 which have tapered outersides and rounded ends. The movable jaw I9 is provided with a concave"inner longitudinal gripping groove 21, while the stationary jaw ll has afiat gripping surface 26. It will be understood that either or both ofthe front 'end'jaw portions 24, 25 may be provided withconcavegrooves'such'as the groove The opposed surfaces of the" front endportions 24, 2 5 are provided just'forwardly of the plates 20, 2|, witha pair of transverse bores 28, 29 which serve as sockets fora coil,spring 30, by which the portions 24, 25 will be urged apart.

In order to clamp a fish hook H between the end portions 24, 25,provision is made of a circular cam member 3| which is eccentricallypivoted in a slot 3m in the rear end of the movable jaw IB by means of apin 32. The cam member 3| is adapted to coact with an abutment in theform of a ball bearing 33, preferably of steel, which is movably held ina tapped bore 34 in the stationary jaw ll. The periphery of the cammember 3| is provided with a groove 35 having the same cross sectionalcurvature as the surface of the ball 33, whereby a good bearingengagement may be obtained between the ball 33 and the cam member 3|,and friction will be minimized.

The ball 33 is held in the bore 34 by means of an adjusting backingscrew 36 which is located in the outer end of the tapped bore 34,whereby the position of the vise jaws ll, l9 may be adjusted as desired.

Provision is made of a jam nut 31 engaged on the outer portion of theadjusting screw 36, whereby said screw will be locked in adjustedposition.

The cam member 3A is provided with a radially-extending handle in theform of a lever 38, which is bent to provide an angular portion, so thatwhen the vise jaws ll, I9 are in position to clamp the fish hook H, thehandle 38 will be disposed substantially in alignment with Said jaws andwill not obstruct the movements of the operator during the operation oftying a fly F upon the hook H.

Operation centric cam member 3| will produce the desired;

clamping action of the forward jaw portions 24,

25 upon a hook H therebetween. It will be understood that the jam nut 31maybe tightened to prevent an accidental change-in the adjustment of thescrew 36, and that further adjustment of this screw will b unnecessaryduring the use of the device, unless it is desired to clampfish' hooks Hof a different size.

One advantage of this invention is that the fish ho k H e clamped .fiynposi i n bya single motion-of. thehandle .38 and may be released by, asingle movement of the handle in the reverse direction.

A further advantageis that the vise williirmly hold fish'hooks in aconvenient position so that feathers, hackle, rand-other desired Ifly.material may be attached thereto, by cement, thread, or any othe d s redmeans- While there has. been disclosed in this specification one form inwhich the invention may be embodied, itisto be understood that this formisshown for the purpose of illustration only, and that the invention isnot to be limited to the spe- Qific' disclosure, but may be modified andembodied in various'other forms without departing from its disclosedfunction. In Short, the invention includes all the modifications andembodi- 'men'ts coming 'within the scope of the following claim.

Having"thus"fully' described the invention,

what is claimed as new and for which it is d= sired to secure LettersPatent is:

In a fly-tying vise, a stationary jaw, a movable jaw pivoted thereto,and means for clamping a hook between the outer end portions of saidjaws, said clamping means comprising an eccentric cam member rotatablymounted on the other end of onevof :said jaws andtan'zadjustableabutment comprising a ball bearingina tapped bore located in the otherend of the other of said jaws, said cam member having a peripheralgroove engaging said ball bearing, and said bore having a screwadjustably mounted therein to serve as a backing for saidball bearing."7
